' To all whom it may concern Be it known that I, MARYE; ANoEnsoN, a citizen of the United States, residing at Washington, in the District of Columbia,"

have invented certain new and useful Improvements in Polishing Machines, of which the following is a. specication.

The invention relates to improvements in a polishing machine, particularly adapted for domestic uses in oiling and polishingV floors and the like.

It is a primary object of the invention to provide a portable polishing machine adapted to be moved over a Hoor, and having means for applying an oil or similar polishing material to the floor and during the same operation to rub or polish the surface -to which the oil is applied.

With h the foregoing conception in mind, the invention broadly coniprchends a floor polishing machine having a .rotating roller for continuously applying an oil to the ioor with a rectangular polishing member carried by the machine and positioned in the rear of the rolle-r for polishing the surface to which the oil has been applied.

It is a further object of the invention to provide a machine of this character, which is exceedingly simple in structure, yet one that is thoroughly efficient in operation and is inexpensive to manufacture.

y In the accompanying drawings:

Fig. 1 represents a side elevation;

Fig. 2 represents al sectional view; and

Fig. 3 represents a detail view of. the polishing pad.

Referring now more particularly to the drawings, wherein like reference characters indicate corresponding parts, the numeral 1 designates the housing of the machine, which may be composed of wood, metal, or the like. This housing is provided with downwardly depending front and rear portions 2 and 3. respectively. The housing preferably resembles in outline the housing of the Well known carpet sweepers, etc.

Mounted within the housing 2, and supported thereby, is a rotary oil applying roller 4, the same having extensions 5 seated .in bearings in the side walls of the housing stead of felt any absorbent material may be used, and the construction of the roller 4 may likewise be materially altered. The roller, however, is preferably so journalled as to freely rotate in the housing for the purpose of applying a liquid oil or the like to the floor surface with which the periphery of the roller contacts when the same is in use, it being appreciated that the roller projects beyond the edges of the downturned ends 2 and 3 of the housing 1.

Positioned in the housing 1, immediately behind the roller v4, there is provided a rec- 4tangular polishing element 9, t-he same being maintained in position in the housing so that free movement thereof is provided. This polishing element, by being of a rectangiilar form, presents four surfaces of equal dimensions, so that said surfaces can be successively used for contacting with the oiled Hoor when the apparatus is in use. The polishing element 9 may consist of wood, metal, or the like, and is encased or surrounded by a laye-r of polishing materiah such as afabric, felt, or the like, as indicated by -the reference character l0. The ends of the materia-1 are united in a. transverse groove 11 by means of a binder strip 12. The material can be easily replaced whenever it becomes worn or unsatisfactory in use by merely removing the binding strip 12. -The polishing element 9 at one end is formed with a bearing 13,v which enters a socket in the side wall of the casing or housing 1. The opposite end of said pad, however, is formed with a rectangular extension 14 disposed within a comparatively large opening 15 in the opposite side of the casing, and to prevent rotation of this pad when the device is in use, I provide a fastening member 16 carriedby the resilient arms 17. This fastening element consists of a rectangular knob and engaging the rectangular extension 15 so as to prevent a, turning thereof when the parts are in position. However, by flex` cle is provided with a central valve 19 having a threaded shank 20 and a handle 2l.

By turning the handle the valve may be raised variable distances to control and regulate the discharge of oil or other polishing material from said container. To secure a uniform application of the oil transversely across the polishing roller 4, the housing l is provided with a transverse pocket or depression 22 extending the entire length of the oil receptacle 18 and receiving the oil from the oil receptacle 18. This pocket is perforated with a row of perforations 23 near its up er portion and adjacent the roller 4, so that a body of oilmust accumulate in the ocket 22 and will then be uniformly discharged through all of said openin in said pocket wherebyan uniform application of oil is imparted to the fabric covering the roller 4. The housing 1 is provided With the usual handle 25, by which the entire apparatus is moved across a floor or other surface, during which time the same operates in the following way. The valve 19 is adjusted so as to permit oil to escape into the trough or pocket having the perforations 23 therein. The userthen begins to move the apparatus over the floor, and this oil discharges onto the fabric covered surface of t-he roller 4. The roller rotates and the absorbent material thereon applies the oil or polish to the floor surface con` tinuously in an even and uniform manner.

It will be appreciated that as the housing 1 is being moved, and as the oil is being applied, the polishing element 9 is likewise in contact with the floor, and one of the fia-t surfaces of this element exerts a rubbing or polishing action on the surface of the Hoor which has just received its oil coating. This means that by the use of a. sin le apparatus the polishing material is app ied, and the surface of the floor is at the same time finished or polished by reason of the adjacent polishing element 9. This operation continues until the polishing surface of the element 9 has become too thoroughly saturated with oil to properly polish the floor surface, whereupon this element is rotated 90 degs. to present an adjacent flat surface, which is perfectly dry and Will properly function to polish the door. This is accom lished by means of the fastener 16, which as heretofore been described.

Having thus described my invention, what ing a po ishing substance to the iioor to be.

treated and an adjustable rubbing element carried by said housing disposed behind said polish applying means, said rubbing element consisting of a rectangular member, means for holding s-aid element in its different adjusted positions whereby different viat surfaces of said member may be caused to Contact with the surfaces to be polished.

3. A ioor polishing machine, comprising a housing, means carried thereby for applying a polishing substance to the floor to be treated, said means comprising a roller, and a rubbing element carried by said housing disposed behind said polish applying means, said rubbing element consisting of a rectangular member, means for holding the same in different adjusted positions whereby diiierent iat'surfaces of said member may be caused to contact with the surfaces to be polished.

4. A machine of the character described, comprising a casing, means carried thereby for applying a polishing substance to a surface over which said casing is moved, a rubbing element disposed in said casing adjacent said polish applying means, said rubbing element having a plurality of flat rubbing surfaces and means for mounting the rubbing element whereby different surfaces may be presented at different times for contact with the surface to be polished.

In testimony whereof I aiiix my signature.
